Shin Godzilla (シン・ゴジラ Shin Gojira) is a kaiju that appeared in the 2016 Godzilla film, Shin Godzilla. It is the eleventh onscreen incarnation of the character. This was the tallest incarnation of Godzilla in film as of the release of Shin Godzilla, but was surpassed by the Godzilla from the GODZILLA anime trilogy. Shin Godzilla is unique among most other Godzilla incarnations in that he is a completely new species spawned by nuclear waste dumping, rather than an ancient creature roused by nuclear testing. Shin Godzilla was mutated by feeding on nuclear waste dumped into Tokyo Bay in the 1950's, which gave it the unusual ability to mutate its own DNA and rapidly evolve itself to adapt to new situations. Shin Godzilla remained underwater until 2016, when it suddenly developed legs and came ashore in Tokyo, leaving behind a trail of destruction. Godzilla evolved once again into a third form before returning to the ocean. It later returned in a larger fourth form, which annihilated a large portion of Tokyo with atomic rays generated by its body before entering a state of hibernation. Anticipating a nuclear strike against Tokyo by the U.S. to destroy Godzilla before he reawakened, a ragtag team of Japanese bureaucrats and volunteers enacted a complex plan codenamed Operation Yashiori, which succeeded in disabling Godzilla's blood cooling system and freezing him solid. While Godzilla was halted for the time being, the American government warned that the nuclear strike would commence once he began moving again.
